Wipe out root rot and biofilm in a single treatment Alien Root Rot X is a fast-acting root steriliser for every hydroponic method, including RDWC, DWC, flood & drain, drip feed, NFT and rockwool. Its active ingredient is hypochlorous acid (HOCl), a powerful biocide with bactericidal, fungicidal, virucidal and sporicidal action that is 99.9999% effective against all stages of bacterial colonisation on roots, equipment and waterlines. Unlike most HOCl products it is manufactured completely stable and stays stable once opened. Key Benefits 99.9999% effective against all stages of bacterial colonisation on roots, equipment and waterlines Kills the widest spectrum of pathogens, including Pythium, in a single pass Removes established biofilm in one treatment rather than masking it Free from harsh chemicals such as aldehyde, alcohol, bleach and QACs Shelf-stable formula that holds its potency even after the bottle is opened Root rot and slimy biofilm choking your system? In recirculating systems root rot and bacterial biofilm spread through pipework and starve roots at the exact point where uptake matters most. Root Rot X sterilises the whole system, clearing pathogens and biofilm from roots, lines and equipment for a clean reset instead of a symptom fix on the plant.
